This study, conducted by AECOM, consisted of a records and literature search at the South Coastal Information Center (SCIC) and archaeological field survey of 11 locations, and preparation of a draft and final report. The cultural resources inventory in support of the Buena Vista Lagoon Enhancement Project Environmental Impact Report was conducted on July 10 and 11, 2014. Three alternatives, one with two options, are proposed that would each include dredging of channels, grading within the lagoon to raise or lower elevations, vegetation removal, improvements to and use of staging areas, and
